STRINGER AND TIE FASTENER.

SPECIFICATION forming part of Letters Patent No. 353,624, dated November30, 1886.

Application filed March 522, 1886. Serial No. 196,113.

TO'aZZ whom it may concern:

Be it known that I, J A0013 \VALTER CROW, a citizen of the UnitedStates, residing at Arkadelphia, in the county of Clarkand State ofArkansas, have invented certain new and useful Improvements in Stringerand Tie Fasteners; and I do declare the following to be a .full, clear,and exact description of the invention, such as will enable othersskilled in the In art to which it appcrtains to make and use the same,reference being bad to the accompanying drawings, and to the letters andfigures of reference marked thereon, which form a part. of thisspecification.

Hy invention has relation to stringer and tie fasteners; and it consistsin the device hereinafter fully described and set forth.

I11 the accompanying drawings, Figures 1,

2, 3, and 6 are views showing the various shapes in which I may firstcut the metal used in making my invention. Fig. 4 is a perspective viewof my completed fastener. Fig. 5 is a longitudinal sectional view of atrestle work, showing a number of my fasteners in 'position.

My invention is described as follows: The stringer and tie fastener 1may be cut out of any desired thickness of metal, and of any size orshape conformable to the conditions necessary to the properperformauceof the duties required of it and to the material upon which used, ashereinafter set forth. The plates 2, 3, I, and 5, after having been cutin the desired shape, have two of the diagonal corners, 6, bent down atright angles to the face of said plate and parallel to each other, andthe remaining two diagonal corners, 7, are turned up at right angles tothe face of said plate, and parallel with each other, and at rightangles with the points 6, thus making a complete fastener, 1, as shownin Fig. 4.. The form of the plate, as shown in Fig. 6, is square, asegment being cutout of each side, as indi cated by the dotted lines a.The points 6 and 7 are then turned down and up, being bent on thedoubledotted lines b. In bending the corners (3 and 7 to theirrespective angles I bend them on such lines that the corners 6,

(No model.)

which are turned down, may be somewhat longer than the corners 7, whichturn up, to enable the builder or repairer to dislodge or draw out theupper points, 7, of the plate 1, from the under side of the timberwithout drawing or loosening the points 6 from the lower timber.

These tie-fasteners are designed to take the place of the old drift-boltand linespike, and are used as follows: Place upon the stringer 8 one ormore of the fasteners, with their long points 6 turned down and runningwith the grain of the w0od,drivethe same home until the under side ofthe plate rests against the face of the stringer, and then upon the twopoints 7,which point upward, place a tie, 9, and drive the same home.The two points 7, running 6 exactly opposite to the two long points 6will also run with the grain of said tie, and hold the same ascfl'ectually and securely asif bolted in place. The stringer 8 isfastened to the abutment in the same manner.

The points of said fastener fitting closely in the grain of the woodprevents water from getting in and rusting said points, and the plate ofsaid fastener prevents the timbers from fitting closely down, face toface, but causes a small space to be left between them, which allows ofa free circulation of air, and thereby prevents the timbers rot-ting.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, 1s

A stringer and tie fastener, 1, being made of a plate of metal, as abovedescribed, having the shorter points, 7, turned up and perpendicular tothe face of the plate and parallel with each other,and its longerpoints,6, turned down perpendicular to the face of said plate andparallel with each other, substantially as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.
